What is GraphQL?

GraphQL is a query language and runtime for APIs that provides a complete and understandable description of the data in your API. It gives clients the power to ask for exactly what they need and nothing more.

Key GraphQL Concepts:

🔍 Queries

  • • Read data from the server
  • • Specify exactly what fields you need
  • • Nested queries for related data
  • • Arguments and variables

✏️ Mutations

  • • Modify data on the server
  • • Create, update, or delete operations
  • • Return modified data
  • • Input types for complex data

📡 Subscriptions

  • • Real-time data updates
  • • WebSocket connections
  • • Event-driven architecture
  • • Live data streaming

📋 Schema

  • • Type system definition
  • • API structure and capabilities
  • • Field types and relationships
  • • Query validation rules

Benefits of GraphQL:

🎯 Precise Data Fetching

Request exactly the data you need, reducing over-fetching and under-fetching.

🔄 Single Endpoint

One endpoint for all operations, simplifying API management.

📱 Client-Driven

Clients control data shape and size, perfect for mobile and web apps.

  • • Implement query depth limiting
  • • Add query complexity analysis
  • • Use variables for dynamic queries

Schema Design

  • • Design schema first, implementation second
  • • Use descriptive field and type names
  • • Implement proper error handling
  • • Document your schema thoroughly
